early 20th century: probably from the verb scramble.
wiktionary
Probably either:
Uncertain; the verb is possibly derived from etymology 1. [2] It has been suggested that the word is an acronym for phrases like “safety control rod actuator mechanism”, “safety control rod axe man”, and “safety control rods activation mechanism”, but these are most likely backronyms.
The noun is probably derived from the verb. [3]
The verb is a variant of dialectal English scramb(“to pull or rake together with the hands; to gather a handful of something from the ground; to scratch with the claws or nails; to pull down violently; to tear off; to maul about; a handful of something from the ground”), possibly related to Dutch schrammen(“to graze, scratch”) [4] and German schrammen(“to scratch, scrape”); see etymology 1.
The noun is derived from the verb.
Origin unknown. [5]
